Hi all. I've had a Predator Helios 300 since March 2019 and I've had a weird issue the entire time. At random times while running any game (on any graphics setting), the framerate will drop to 5 fps for several seconds before slowly climbing back up to 60+ over the next minute. During the lag spikes, the gpu usage rises to 100% and the temp drops a few degrees. But I've seen this happen at 50 degrees C so I don't think it's a heating issue.
I've already tried several possible solutions. I did a fresh windows install to get rid of bloatware. I updated drivers. I rolled back drivers. Disabled every overlay I could find (windows, steam, nvidia, etc). Tweaked power settings. Tweaked nvidia control panel settings. I set the fans to max while also using an external cooling pad. I disabled the cpu turbo using throttlestop. So far nothing has fixed the issue.
At this point I'm out of ideas. Is this a known issue? Is there any further troubleshooting I could try?
